DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings and initially to FIGS. 2-4, an exercisingmachine in accordance with the preferred embodiment of the presentinvention comprises a main frame 10, an upright post 40 mounted on afront portion of the main frame 10, two swinging handles 50 each havingan upper end pivotally connected with the upright post 40, a cyclemovement mechanism 20 mounted on a rear portion of the main frame 10,two pivot members 30 mounted on two opposite sides of the cycle movementmechanism 20, two links 60 each having a first end pivotally connectedwith a lower end of a respective one of the swinging handles 50 and asecond end pivotally connected with a respective one of the pivotmembers 30, two pedals 70 each mounted on a respective one of the links60, and two adjusting members 80 each pivotally mounted between arespective one of the links 60 and a respective one of the pivot members30.

The pivot members 30 misalign with each other and are located atdifferent positions of the cycle movement mechanism 20. Each of thepivot members 30 is mounted on the cycle movement mechanism 20 in aneccentric manner. The swinging handles 50 are located at two oppositesides of the upright post 40.

Each of the adjusting members 80 has a substantially inverted U-shapedprofile and has an interior provided with a receiving space 81. Each ofthe adjusting members 80 has a first portion pivotally connected withthe respective pivot member 30 and a second portion pivotally connectedwith the second end of the respective link 60. The first portion of eachof the adjusting members 80 is provided with a mounting sleeve 31pivotally mounted on the respective pivot member 30. The second portionof each of the adjusting members 80 is provided with a plurality ofadjusting holes 90.

Each of the links 60 is pivotally connected between a respective one ofthe swinging handles 50 and a respective one of the adjusting members80. The second end of each of the links 60 is provided with a pivotportion 61 pivotally connected with one of the adjusting holes 90 of therespective adjusting member 80. The pivot portion 61 of each of thelinks 60 is received in the receiving space 81 of the respectiveadjusting member 80.

In operation, referring to FIG. 5 with reference to FIGS. 2-4, when auser operates the exercising machine, his hands can hold the swinginghandles 50 to move the swinging handles 50 and his feet tread the pedals70 to move the links 60. In such a manner, the links 60 are driven byrotation of the cycle movement mechanism 20 and by pivotal motion of theswinging handles 50 so as to perform an oblong orbit movement so thatthe user can exercise his hands and legs. Thus, the links 60 and theadjusting members 80 are driven by the swinging handles 50 to moveforward and backward so that the links 60 and the adjusting members 80are disposed at a linear state.

Referring to FIGS. 5-7 with reference to FIGS. 2-4, the pivot portion 61of each of the links 60 is pivotally connected with one of the adjustingholes 90 of the respective adjusting member 80 so that each of the links60 is located at different positions to change the positions and anglesof each of the swinging handles 50 so as to provide different exercisingeffects.

Accordingly, each of the links 60 is pivotally connected with aselective one of the adjusting holes 90 of the respective adjustingmember 80 to change the position and angle of each of the links 60 andeach of the swinging handles 50 so as to adjust the movement trace ofeach of the links 60 and to provide different exercising modes, therebyenhancing the exercising effect of the exercising machine.

Although the invention has been explained in relation to its preferredembodiment(s) as mentioned above, it is to be understood that many otherpossible modifications and variations can be made without departing fromthe scope of the present invention.
